[Sound and velocity DPOAEs : Technology, methodology and perspectives].
Review in HNO, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recent publications show that DPOAE measurements can generate a more accurate diagnosis, if (1) their fine structure is suppressed, and (2) if the calibration of the sound field is improved. Reduction of the fine structure is particularly important in the frequency range below 4 kHz in subjects with intact cochlear amplifier and can reduce the standard deviation of threshold estimations based on DPOAE-input/output functions from 11 dB to 6 dB. Improving the sound-field calibration has most impact in the frequency range above 4 kHz. Threshold estimations based on laserinterferometrically measured DPOAE input-output functions where the sound field was calibrated close to the tympanic membrane have been shown to reduce the standard deviation down to 8.6 dB in humans and 6.5 dB in guinea pigs. Compared with conventional DPOAE measures, such as amplitude or signal-to-noise ratio, threshold estimation based on DPOAE-I/O functions has the advantage that its slope provides additional information about the middle-ear; however, its specificity is limited. In the future, combined methods such as acoustic reflectance or laser vibrometry on the umbo promise a reliable assessment of the middle-ear contribution to DPOAE.
